>         DEVTREE_CONST struct device *needed_eeprom;

> Now in the dt, we'd name the referenced device, but only

> device i2c 0x50 alias my_eeprom on end
>
> The author of the dt would be free to choose this name.
> Later, when configuring the driver in the dt we would
> associate this given name with the one in the `chip.h`:
> chip some/chip/driver

Meh, https://review.coreboot.org/16080
If we have code at the mainboard level that needs a device
reference (e.g. smbios_mainboard_serial_number()) how could
that be handled? any ideas? revert to mb/chip.h?
